Does your brother even know that you were sexually abused as a child? - If NO, then maybe start out by telling them that you feel that you are having to deal with all these mental issues (in the here and now) for you were sexually abused as a child and for many years.... and then see how they react to this information before you decide to go out on a limb and tell it all.

I suggest this path, for many family members will turn on the abused one at first - they need someone to blame at first, not to mention time to deal with all they were just told... please keep yourself safe until you know for sure how your brother and his wife just might react.

Take-Care.................. ((( hugs )))
